ANTITHEFT DEVICE FOR MOTOR VEHICLES.

Application led February 18, 1924. Serial No. 693,426.

My invention relates to key controlled mechanisms and particularly but not eX- clusively to a key controlled mechanism for cont 1olling the actuating mechanism of a motor vehicle.

My invention will be best understood from the following description when read inv light of the accompanying drawings showing one specific embodiment of my invention selected for illustrating purposes, while the scope of my invention will be more particularly pointed out in the appended claims.

'in the drawings z- 1 shows a front View of an ignition switch;

Fig. 2 is, a section onthe line 2-2 of Fig. l;

3 i., a fragmentary section on the line 3-3 of 2 with the back plate removed;

Figs. 4; and 5 are sections corresponding to 3 but respectively showing the parts in different positions; n

Fig. 6 is a section on the line 6 6 of Fig. 3; y

7 is a section on the line F 6; and Y Fig. 8 shows a det-ail.

Referring` to the drawings, which show the particular embodiment of my invention se-k lected for illustrating my invention, I have shown a casing 1 which in practice is attached in the usual manner to the instrument hoard of a motor vehicle the casing having a front plate 3 and a removable back plate 5.

Extending through the casing is a shaft i which at its forward end carries an operating lever 9 so that the shaft may be rotated. learwardly of the Vcasing the shaft is attached to a valve l() of the turn-ing plug type mounted in a valve casing 1l", and interiorly of the casing tlie shaft 7 carries switch mechanism 13.

in practice the switch mechanism 13 is employed for establishing or interrupting the ignition circuit, while the Vfuel controlling valve 10 is employed for establishing or interrupting communication between the engine and the fuel supply, thevalve casing ll as illustrated being placed in a pipe line tion switch can be eliminated by placing the fuel controlling valve in the engine intake pipe between the carburetor and the engine. In practice when the operating lever 9 is yin Vits intitial position indicated by full lines in Fig. l the switch mechanism 13 will interrupt the ignition circuit and the valve 10 will interrupt the engine fuel supply so that the motor will be rendered inoperative. vWhen the controlling lever is moved to its final position indicated by dotted lines inv Fig. l the ignition circuit will be established and likewise the fuel supply will be established, thus rendering the motor operative.

1t will of course be understood that either the valve or ignition switch maybe omitted; and that my invention not only may be applied to any controlling mechanism for rendering the actuatino' mechanism of the motor vehicle operative or inoperative,V but may be applied to other forms of controlling mechanism as for example switches for lighting circuits and the like.

, Referring part-icularlyv to Figs. 2 to 5 l. have shown a dish 17- carired by the shaft .7 interiorly of the casing, the disk being formed with an integral Vhub portion 19 secured to the shaft by a set screw 21, As indicated in Figs. 2 to 5 inclusive the disk i7 is provided at its periphery with a notch 23. the notch providing a shoulder 25. Carried by the casing 1 and integrally formed therewith isa tubular part 27 which carries a reciprocatory bolt 29 adapted to enter the notch 23 and abut the shoulder 2 5 for lock? ing the shaft 7 against rotation when the operating lever 9y is in its initial position as illustratedV by full lines in Fig. 1. Beneath the bolt 29 is a compression spring 31 which presses the bolt outwardly so that it will automatically snap into the notch 23 when the control lever 9 is moved into its initial position. Y

For preventing unauthorizedv operation of lso ing the notch 23. It will be further observed that I have provided a key controlled lock exemplified by the barrel 33 with its associated deteiits 47 and tumblers 53, an-d have provided a secondary lock as exemplified by the bolt 73 Which engages the recess 71 of the barrel. Y

It Will be observed that in using a device constructed according to my invent-ion the operator ot the vehicle Will first insert the rey and turn the barrel from its initial to its inal posit-ion, which will unlock the operating handle so as to permit it to be turned from its yinitial to its final position and thus enable the motor to be started. However beitore the operatingy lever can be moved from its initial to its irinal position the key must be removed from its operating` position in the lock, and when the motor is stopped Vby turning'the operating` lever from its final to its initial position the: device automatically looks Without reinsertion ot the key. This operation by enforcing Withdrawal ot the key from its operative posi` tion in the lock thus forcing the operator to move the key in the direction in which it is Withdrawn insures that the key will be Withdrawn before the motor is started andv therefore Will not be left in the lock after the motor is stopped.

It is believed that the operation of the device Will be clear from the foregoing`I description. Briefly however Fig. 3 shows the parts in the locked position, the barrel being' in its initial position and the bolt Q9 preventing movement ot the operating leverV from its initial position. Fig. t shovvs the parts in the position after the barrel has been turned to its final position and the key ufithdrarvn` under which conditionstbe bolt 29 vvill have Withdrawn from the notch 23', and the bolt 7 3 Will have entered the .recess 71 sol as to prevent the bolt 29 snapping back into the notch 23. In the position shown by Fig. 5 the operating lever has been moved to its inal position land the bolt 73 has been withdrawn from the notch 7l. which releases the barreland permits the bolt 29 to move against the cylindrical portion ot the disk 17. In cases Where the barrel' turns freely the movement of the bolt 29 tromthe position shown by Fig. 4 to that shown by Fig. 5 is `suilicient lto throw the barrel into its initial position, as illustrated in Fig. 5y but' if this has' not occurred the barrel will be turned to its initial position when the belt Q'Qrsnaps into the notch 23 upon moving the operating lever back to its initial position.

Although IY have described for purposes of ii'lustration one speciiiov embodimentot my invention it is to beV understood that I ani not limited thereby to itsparticular mechanical details, but that` Within the scODe of my invention Wide deviations may 'be made therefrom Without departing from the spirit ot my invention.
